Description

Cooling structure of coupling machine

The present invention relates to a heat dissipating structure of a coupling machine, and more particularly to an improved structure between a coupling disc set and a heat dissipating fin which can increase heat dissipation efficiency.

Generally, the permanent magnet coupling machine is mainly composed of a magnetic conductive rotor made of copper or aluminum and a permanent magnet rotor with a strong magnet. The magnetically permeable rotor is mainly fixed on the motor shaft, and the permanent magnet rotor is fixed on the load shaft, and there is a gap (commonly referred to as an air gap) between the magnetic permeable rotor and the permanent magnet rotor. In this way, the connection between the motor and the load is converted from a soft (mechanical) connection to a soft (magnetic) connection. By adjusting the air gap between the magnetically permeable rotor and the permanent magnet rotor, the output torque variation on the load shaft can be achieved. The load speed changes.

The permanent magnet coupling function can significantly improve the operating characteristics of the system. The permanent magnet coupling drive motor is started at no load before starting the load, which not only reduces the starting current of the motor and reduces the thermal shock load on the motor and the influence on the power system. Thereby saving electric energy and prolonging the working life of the motor, and extremely effectively reducing the destructive tension of the transmission system on the conveyor belt during startup, eliminating the shock generated when the conveyor is started, and greatly reducing the start of the transmission system itself. Shock, extended belts, idlers and other critical lifespans have improved the safe and reliable operation of the equipment, effectively reducing equipment maintenance and downtime costs. Therefore, compared with the traditional coupling machine, the permanent magnet coupling machine does provide a more advanced structure, which is extremely practical.

When any mechanical structure is in operation, heat is generated by friction, and the permanent magnet coupling is no exception. Generally, the conventional permanent magnet coupling machine is provided with heat dissipating fins on the rotating disc of the permanent magnet rotor. When the permanent magnet coupling rotates at a high speed, the heat radiating fins can be used to heat the permanent magnet coupling machine. Dissipate to avoid excessive temperature and damage to mechanical components during operation.

However, the conventional magnetic permanent magnet coupling described above still has disadvantages in the heat dissipation process and needs to be improved:

1. The heat-dissipating fins of the conventional structure are flat on the turntable and then locked with screws. Therefore, there may be a gap between the heat-dissipating fins and the turntable, so that the heat on the turntable cannot flow smoothly to the heat-dissipating fins, thereby affecting heat dissipation efficiency. .

2. The heat-dissipating fins of the conventional structure have a limited contact area with the turntable, which also affects the heat dissipation efficiency.

To this end, the Applicant has developed the heat dissipation structure of the invention coupling shaft in view of the heat dissipation problem caused by the above-mentioned conventional permanent magnet coupling machine, adhering to the spirit of research innovation and excellence, and using its professional vision and professional knowledge.

The main object of the present invention is to provide a heat dissipation structure of a coupling machine. The heat dissipation fins extend out of the conductive block, so that the conductive block is inserted into the turntable of the coupling machine, and the adhesion and contact between the heat dissipation fin and the turntable are increased. The area allows the heat of the coupling machine to be efficiently operated to the elimination of the fins, improving the stability of the coupling operation and prolonging the service life.

Another object of the present invention is to provide a heat sink junction of a coupling machine The device is inserted into the turntable by the conductive block, so that the device for the heat sink fin is more rapid and stable.

In order to achieve the above object, the invention adopts the following technical solutions: A heat dissipating structure of a coupling machine mainly includes a turntable, and a plurality of heat dissipating fins are disposed on one side of the turntable, and the heat dissipating fins are arranged around the turntable with the rotating shaft axis in a ring shape, and the heat dissipating fins are A conductive block extends in the direction of the turntable, and a slot is provided in the turntable relative to the conductive block, so that the conductive block is inserted into the slot.

The heat-dissipating fins of the conventional coupling machine are flat on the turntable, and are limited by the fixing method. There is a gap between the heat-dissipating fins and the turntable, which blocks the heat transfer, so that the heat-dissipating efficiency is greatly reduced. In the manner of the present invention, the heat dissipating fins are easily inserted into the turntable to improve stability and tightness, so that the conductive block directly transfers heat on the turntable to the heat dissipating fins for effective elimination.

In addition, due to the arrangement of the conductive block, the heat dissipation area between the heat dissipation fin and the turntable can be increased to further improve the heat dissipation efficiency.

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The heat-dissipating fins 1 extend toward the turntable 2 with a conductive block 3, and the conductive block 3 can be integrally formed with the heat-dissipating fins 1 . The conductive block 3 is provided with a slot 21 on the turntable 2 for the conduction. The block 3 is inserted into the slot 21 to adhere the heat dissipating fin 1 to the turntable 2, and then fixed by screws (not shown) or the like.

With the foregoing design, when the coupling is in operation, the heat generated by the coupling can be dissipated by the turntable 2 through the conductive block 3 to the heat dissipation fins 1 to maintain the stability of the work.

In order to improve the heat dissipation efficiency, the heat dissipation fin 1 must be closely attached to the turntable 2, and the heat dissipation fin 1 and the turntable 2 can be improved by the fixing manner of the conductive block 3 inserted in the slot 21 in the present invention. The degree of closeness. Even when the turntable 2 is operated at a high speed, since the conductive block 3 penetrates into the turntable 2, the heat radiating fin 1 can maintain good adhesion and obtain good heat dissipation efficiency.

In addition, the conductive block 3 is extended by the heat dissipation fins 1 , so that the conductive block 3 can penetrate the assembly structure of the turntable 2 to increase the heat dissipation area between the heat dissipation fin 1 and the turntable 2, and further Improve heat dissipation efficiency.

In order to maintain good fixability, the conductive block 3 is disposed with the slot 21 One or more, as in the present embodiment, are disposed at the front and rear ends of the heat dissipation fin 1 so that the heat dissipation fin 1 does not shake when the turntable 2 is operated at a high speed. The shape and size of the conductive block 3 and the slot 21 are adjusted as needed, as long as the stability of the heat dissipation fin 1 is maintained and the heat dissipation area is increased.

In addition, referring to FIG. 6 and FIG. 7 , the inventors have found that in addition to the front surface of the heat dissipation fin 1 , a small auxiliary heat dissipation fin 4 can be added to the back surface of the turntable 2 relative to the position of the heat dissipation fin 1 . The heat-dissipating fins 4 are smaller in size than the heat-dissipating fins 1 , and the fixing manner is not limited. The heat-dissipating fins 1 and the auxiliary heat-dissipating fins 4 are disposed on both sides of the turntable 2 to achieve an optimal heat dissipation effect. The auxiliary heat dissipating fins 4 are not limited to the number and position, and are generally disposed on the periphery of the back surface of the turntable 2. Therefore, it is necessary to avoid the original frame 22 on the back side of the turntable 2.
